Engineering Contradiction Analysis
1Reliability
If traditional electrical connector design is used, then device complexity is low, but shielding performance is poor leading to signal interference
Solution Approach 1:
The patent implements nested shielding structures where the first shielding component is positioned within the second shielding component, and the third shielding component is positioned within the second shielding component. This nested arrangement provides multiple layers of electromagnetic shielding without significantly increasing overall device footprint, effectively blocking EMI and noise crosstalk while maintaining a compact connector design.
Solution Approach 2:
The shielding structure is divided into multiple independent components (first shielding component, second shielding component, third shielding component) that can be separately manufactured and then assembled. Each shielding component serves a specific function in different regions of the connector, allowing for optimized shielding performance at each segment while maintaining manufacturing feasibility.
